ROLLER SLUICE.

Application filed September 11, 1922. Serial No. 5557;4(17.

Roller slu-ices areknownin which atthe beginning of the lifting. movement the sluice.

is loosened at-the jointing surface of the masonry in order .to reduce the considerable first resistance from friction which is caused by rusting. after long interruptions of serv ice.

Thisl'oosening .of the sluice board is ef fected, accordingto the, invention, with the aid of a I3111L1T18Cl12111l8l11 slidingrupoii guides.

In order. that thednvention may be clearly.

understood l shall hereinafter proceed to describe thesame with reference to the; form of construction. shown by: way of example on,

the. accompanyingdrawing, wherein Fig. l is a perspective view of the roller:

sluice.

Fig. 2 shows on-enlargedscalethe link mechanismtand: the slidable-bearing.v

Theprincipal parts of the roller sluice are the: sluice .boardil whichis in contact. with. llhGFjOlIlitlIlSllPfflC6S 2 of the masonry, the.

pulleys i3 and the winch mechanism 4.. The four-pulleys 3 are unitedvby an iron frame of'flat irons 5 and @by thetwo axles 6 and 7 to forma rolling carriagezwhich. is not rigidly. connected with the sluiceboard 1, but movable withregardto the samein slidable bearingsS, adapted to slide on guide rails 9.

Oneof the"slidable-bearings 8 for the, -pu1-.

leys .3 is shownin Fig. 2 on enlargedscale so that it can beclearly seen from thisfigure how the slidable bearing 8 is insertedinto. its g uide rail-.-9. The movement of the slide ablebearing is lilllltQdibYllllGbfiI'S 40 which areplaced outside =the..U-irons 9 after the. slidable bearingzfi has been inserted. Fig... 2 shows clearly-the upper .and lower sliding .1.

surfaces and thefianges 34 designed to prevent the slid'able: bearing fromj umpi-ng out of'the. guide 'rails. The sluice board is'connected witlrthe rolling carriage at each of.

its fourcorners by means of it'llIlk '10 hing-. edly mounted at one end on thesluice board.

1 and at the votherend on thecorresponding axle-13 and further=by vmeans of a link 11.

hingedly. mounted atone vend'to the same axle .13 .anduat the other end on the. corresponding axlez6 or 7 which connect each one pair-10f pulleys 3 and the corresponding slidab-le jbearingsh8. The. two axleszl3 are rigidly. connected with. one; another by an faces.

inverted U-shaped frame of flat irons li. A pull chain :25 attached to the rolling carsuspended. Two chains 19 attachedto the twoasuspension pointsl20 of the sluice board 1 are guided-over sprocket wheels.21 and have a common counterweightr23-at the free- .ends- -:On the shaft 30 which carries the pulley-16 and-the sprocket wheels 21 a bevel wheel 31 is keyed which, throughtheintermediary. of a vertical shaft 82 carrying bevel wheels 38, 34: is connected with a bevel wheel 85 on the shaft 36 of the winchd.

If the. sluice board 1 is lowered with the aid of winchd the lower pulleys 3- come to rest upon the lower rails 24 and therefore the axles 6 and 7 and alsothe bearings 8 can continue-a trifle to descend as the guide rest-in their height butthe sluice board 1 rails 91 are inclined from their exterior ends v to the. sluice board. This inclination reguthe sluiceboard towards the jointingsurfaces 2 of the masonry with strong pressure as the guide rails 9 slide on the bearmgs 8 and further owing to the pressure exerted by thewater. The chain 15 to whichthecar- 8O .lates'also the direction ofthe-movement of riage is suspended becomes thus slack but the cable-26 to which the frame 14L of the crank mechanism issuspended remains taut as .thelinks 10 and ll must participate in the downward movement of the sluice board 1. Inversely, if the sluice is to be opened, only the chain 26 will be strotc led. As this chain 26 through the-rigi d frame of fiat irons 14 transmitsits movement upon the axles 13 and upon. the links 11, 10 and as the links 11 act on the axles-7, 6 of the pulleys 3 these pulleys are pressed against the rails 27 which are fixed on the masonry 2, whereby the sluice-board is lifted off the jointing sur- At this occasion the il-irons 9 slide again on the slidable bearings 8 whereby the axles 13 are raised so that the pull chain .25 is stretched also andth e rolling frame' board is raised. The sliding back of the U-irons 9 on the slidable hearings 8 is prevented by the stretched cable 26.

Compensating springs 2% adapted to be adjusted by means of screws 29, serve for compensating he unequal lengths of the chains 15 and 19 during the time the sluice board 1 and its Uirons i) execute a relative movement with regard to the slidable bearings 8 and the rolling frame This is necessary if--as is supposed to be the easethe sprocket wheels 21 are keyed on the same axle 30 as the grooved pulley 1(. As soon as the sluice board 1 hangs vertically it is raised by means of winch 4. without any sliding friction, only the pulleys 3 exerting a rolling friction on the rails 97.

I claim 1. An improved roller sluice comprising in combination with the sluice gate, a winch on the top end of said sluice gatega sluice board movable on said sluice gate, pulleys on the sides of said sluice boa d, an axle connecting said pulleys, a. rigidtrame on said axle and forming together with said pulleys a. rolling carriage, upwardly inclii'ied guide rails one for each pulley rigidly fixed on the front surface of said s uice hoard. slidable bearings one for each pulley guided on said guide -ails and mounted on the axle connecting said pulleys, one link for each pulley hingedly fixed on the. front surface of said sluice board. an axle connecting the other ends of said links, links connecting said link axle with said pulley axle, a rigid frame mounted on said link axle. upwardly inclined supportingrails for said pulleys, said rails being fixed on the side *alls of the sluice gate, and means for connecting said two frames with said winch so that at the operation of the winch the closed sluice board is first unseated from the ointing surfaces of the masonry by the action of the link mechanism before it is raised. whilst the lowering of the sluice board said pulleys are stopped by said supports before the sluice board has reached its end position that the sluice board continuing to descend under the action of its weight is strongly pressed by the effect of said inclined rails against the jointing faces of the masonry.

2. An improved roller sluice comprising in combination with the sluice gate, a winch on the top end of said sluice gate, a sluice board movable on said sluice gate, two pairs of pulleys on the sides of said sluice board one pulley at each corner, an axle connecting the pulleys of the upper pair, an axle connecting the pulleys of the lower pair, a rigid frame on said axles and forming together with said pulleys a rolling carriage, i'ipwardly inclined guide rails one for each pulleyrigidly fixed on the front surface of said sluice board, slidable bearings one for each pulley guided on said guide rails and mounted on the axles connecting said pulleys, one link for each pulley hingedly fixed on the front surface of said sluice board, an axle coni'iecting the other ends of the links near the pulleys of the upper pair and an axle connecting the links near the pulleys of the lower pair, links com'iecting said link axles with said pulley axles, a rigid frame mounted on said link axles, upwardly inclined supporting rails for the pulleys of the lower pair fixed on the bottom of the sluice gate, and means for connecting said two "trainees with said winch so that at the operation of the winch the closed sluice board. is first unseatcd from the jointing surfaces of the masonry by the action of the link mechanism before it is raised, whilst at the lowering of the sluice board said pulleys are stopped by said supports before the sluice board has reached its end position so that the sluice board continuing to descend under the action of its weight is strongly pressed by the effect of said inclined rails against the jointing faces of the masonry.

3. An improved roller sluice comprising in combination with the sluice gate, a winch on the top end of said sluice gate, a sluice board movable on said sluice gate, two pairs of pulleys on the sides of said sluice board, one pulley at each corner, an axle connecting the pulleys of the upper pair, an axle connecting the pulleys of the lower pair, a
